Sending Patches

To make changes to the CDT, whether it be code, docs, JUnits, etc., you will need to send patches to the source stored on eclipse.org. Here is the process for sending patches.

To fix anything in CDT first you need to create or find an existing bugzilla report for this particular problem/enhancement

Check out the code from corresponding branch and apply the fix

Create a workspace in Eclipse for your work. Check out the CDT plugins you'd like to work on into it. The plugins are on dev.eclipse.org, /cvsroot/tools under folder org.eclipse.cdt/all. There should be around 40 plugins there that you need to check out. More instruction on how to get started are in Getting started with CDT development article.

Code with any of the warnings/errors mentioned in the policy, including strings externalization and API errors will not be accepted.

To minimize the patch, do not re-format the source code you edited (except changed lines). Do not fix any warnings in the code you are not changing (it is good to fix warnings but it would clutter the patch, you want to solve one problem at a time).

Create a patch "Team->Create Patch" command on changed projects, select Workspace as a scope even when only one file has changed. Ensure that all the modified plugins are included when creating the patch.

If you have new or changed binary files such as icons, attach them separately and indicate where do they go

Check you patch to make sure you did not add anything irrelevant, such as formatting of other code, etc

If you really want to do formatting or styling (such as converting to java 1.5) - create another bug for that and attach a patch

Check size of the patch, if it is more than 250 lines see copyright section below

Submit patch using an attachment to a bug report

Mark attachment as a patch

If previous patches attached to the bug, which are obsolete now mark them as such

Add a comment to which branch the patch should be applied (HEAD by default)

Add a comment on what patch is doing, it is not easy to figure it out from the code

Make sure bug report has a clear reproducible scenario, if not add one

To speed up process of applying your patch you should create one or more junit tests as well and attach as separate patch (or together)

Normally committees are watching new bugzilla activity and somebody would look at your patch in a few days

If the patch has not received an attention in a week or so, some nagging can help. Send email to mailto:cdt-dev@eclipse.org asking committers to look at the patch. Continue sending e-mails until somebody would give up and look.

One of the fundamental rules that Eclipse follows is the ability to trace back who contributed what code and that the person who contributed it has ownership of the code, or has permission from their employer to contribute the code (since employers tend to own everything you write). To help keep this IP integrity going, please ensure your contributions are "clean".

If you copy ANY code or images from somewhere else please clearly state it

If you copy GPL code we cannot take it

If you copy EPL code, preserve the original copyright and contributors

If your changes are more than 250 lines of code patch has to go through IP review process, unless it can be applied by the committer from the same company as you are. Nobody wants to do it so please avoid it. Try to fix one bug at a time.
